HabitAnnual
Growth—

Succeeds in ordinary garden soil[1]. Prefers a well-drained loamy soil in full sun[2]. The plant grows strongly on rich, alluvial soils but is rarely found on sandy soils in the wild[3]. The whole plant has a strongly sweet aroma[4, 3]. This species has a symbiotic relationship with certain soil bacteria, these bacteria form nodules on the roots and fix atmospheric nitrogen. Some of this nitrogen is utilized by the growing plant but some can also be used by other plants growing nearby[2]. When removing plant remains at the end of the growing season, it is best to only remove the aerial parts of the plant, leaving the roots in the ground to decay and release their nitrogen.

Propagation

Pre-soak the seed for 12 hours in warm water and then sow in spring in situ. The plant requires general flooding in order to induce massive germinations in the wild; local flooding will cause little or no germination. It grows particularly well after late summer-autumn or winter flooding[3].
